SLASHER.

Application med October 9, 1925. Serial No. 61,519.

This invention relates to machines known in the textile industry as slashers. Such machines are. widely used for applying sizing or other liquid to yarn or threads. The invention is especially concerned with slashers of the hot air or air drying type.

A hot air Slasher usually includes a mechanism for applying sizingfor other liquid to the yarn, a drying chamber through which the sized yarn is fed, and mechanisms for measuring the yarn and winding it on a beam. The volatile constituents of the sizing or other liquid with which the yarn is treated are evaporated from the yarn as it passes through the drying chamber, the yarn being guided into close proximity to a series of steam pipes which supply the necessary heat for this purpose. l

It will be evident that the output of a given machine is controlled very largely by the length of time required to dry the yarn. Accordingly, the present invention aims to devise a Slasher in which the drying operation will be expedited, and to attain this result without adding seriously to the expense of manufacture of the machine.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.

Referring now to the drawings,

Figure l is a side view of the size applying apparatus and the drying mechanism of a slasher embodying this invention;

Fig. 2 is an end view of the drying mechanism shown in Fig. 1; and

Fig. 3 is a perspective view of one of the air discharging nozzles.

`The machine shown includes a dip tank 2, Fig. 1, of the ordinary construction for applying sizing or other liquid to the yarn. The strands or ends of yarn are arranged side by side forming abroad web indicated at y. Immediately after leaving the dip tank 2 the yarn passes over a guide roll 3 and enters the drying chamber 4. This chamber is constructed substantially in aecordance with the usual practice, and includes a casing in which is located a series of steam pipes 5, these pipes being arranged in horizontal rows. The web y of yarn is guided back and forth in horizontal paths of travel between these rows of steam pipes,

the web being supported and fed by rolls arranged at opposite ends of the drying chamber. In some cases, and as shown, the yarn is brought out of the chamber at an intermediate -point and led through the dip tank 2 a second time. When it is not desired to dip the yarn twice it is guided over a roll 6 similar to the other rolls that supgprt and guide the web. The yarn leaves t e dr ing chamber at the lower part thereof'an passes over a guide roll 7 to a measuring roll 8 and thence travels through a suitable comb and is wound on a beam, neither the comb nor the beam being illust'rated.' The casing of the drying chamber 70 is provided with openings at its opposite ends to permit the passage of the yarn.

The arrangement so far described is substantially like that of the ordinary type oi hot air slasher.

According to the present invention two upright wind trunks 10 and 12, respectively, are located at the opposite ends of the drying chamber 4, these trunks leading, respectively, from blowers 13 and 14 which are 80 mounted on the to of the chamber. Leading from the trun 10 is a series of nozzles 15, arranged one above the other, and each so located as to discharge air horizontally into the drying chamber substantially parallel to and in contact with the webs of yarn being fed through this chamber. A similar series of nozzles 16 leads from the trunk 12 and discharge air horizontally into the opposite end of the drying chamber. As shown, the nozzles direct the air longitudinally of the paths of travel of the yarn.

Preferably these nozzles are of approximately the construction shown in Fig. 3, each nozzle tapering from its intake end to its discharge end so that a substantially uniform distribution of air will be maintained across the entire width of the chamber. In order to further contribute to this result, the wind trunks preferably are arranged at diagonally opposite corners of the chamber, as will be evident from an inspection of Figs. 1 and 2. Located centrally of the chamber and mounted on top of the casing is an exhaust blower 17 which exhausts air 105 from the central portion of the chamber. Y

This arrangement thus maintains a strong forced circulation of air through the drying chamber from the ends toward the central part thereof. It will be evident that the drying of the yarn is greatly expedited and that the drying operation thus can be completed in a fraction of the time that would otherwiseV be required, particularly when the atmospheric humidity is high. The production obtainable from a given may chine thus is increased very substantially ful in treating yarn with gases other than A air, where desired, and the term air, therefore, is used to include other gases which may be handled by the apparatus.

Having thus described my invention, what I desire to claim as new is: y

1. In a hot air Slasher, the combination of a drying chamber, mechanism for guiding and feeding the yarn to be treated through said chamber, and means for creating a strong forced circulation of air through said chamber from the ends toward thel central part thereof.

2. In av hotair Slasher, the combination of a drying chamber, mechanism for guiding and feeding the yarn to be treated through said chamber, a plurality of nozzles arranged to discharge air into said vchamber in a direction approximately parallel with the webs of yarn, and a blower for forcing air through said nozzles.

3. In a hot air Slasher, the combination of a drying chamber, mechanism for guiding and feeding the yarn to be treated through said chamber, a plurality of nozzles arranged one above the other at one end of said chamber for directing air inwardly along the paths followed by the yarn as it 1s fed through said chamber, a wind trunk to which alI of said nozzles are connected, and a blower for forcing air through said trunk and nozzles, said nozzles being tapered from said trunk toward their discharge ends.

4. In a hot air Slasher, the combination' of a drying chamber, mechanism for guiding and feeding the vyarn to be treated through said chamber, a plurality of nozzles at each end of said c amber arranged to discharge air into the chamber in opposite directions approximately parallel with the webs of yarn, and blowers for forcing air through said nozzles.

5. In a hot air Slasher, the combination of a drying chamber, mechanism for guiding and feeding the 4yarn to be treated through said chamber, a plurality of nozzles at each end of said chamber arranged to discharge air into the chamber in oppositel directions approximately parallel with the webs of yarn, blowers for forcing air through said nozzles, and an eX- haust blower for takin air from the central portion of said c amber, whereby a strong circulation of air is maintained through the chamber.

6. In a hot air slasher, the combination of a drying chamber, mechanism for guiding and feeding the yarn to be treated through said chamber, two upright wind trunks located at diametrically opposite corners of said chamber, two sets of nozzles extending, respectively, from each trunk and arranged to discharge air into the chamber in opposite directions,'and blowers for forcing air through said wind trunks and nozzles.
